Plant vs Animal Transport Systems
| Feature | Plants | Animals |
|---|---|---|
| Transport systems | Two separate (xylem & phloem) | One system (circulatory) |
| Transport medium | Water, sap | Blood |
| Pump mechanism | No pump (passive) | Heart (active) |
| Flow direction | One-way (xylem), two-way (phloem) | Circular (closed loop) |
| Speed of transport | Slow (meters/hour) | Fast (complete circuit in ~1 minute) |
| Substances carried | Water, minerals, sugars (separate) | Everything together in blood |
Why Do Plants Have This System?
Plants evolved separate transport systems because:
- Stationary lifestyle: No need for rapid responses like animals
- Energy efficiency: Passive transport saves energy
- Different requirements: Water needs to go up, food needs to go everywhere
- Size constraints: Separate systems work better for very tall plants
